chattr vs Dovetail: at a glance
What is chattr?
chattr deleted every LLM integration it had written and outsourced the lot to ellmer
chattr puts a large language model inside the RStudio IDE, either through a Shiny app or directly at the console. As of 0.3.0 it no longer talks to any model provider itself: all integration goes through ellmer, and the hand-written OpenAI, Databricks and LlamaGPT backends were removed. The package's supported model list is now whatever ellmer supports, and the Shiny app streams responses through ellmer rather than managing a background process.
What is Dovetail?
Dovetail spent July opening doors to other tools and August making its own rooms easier to enter.
August has been a run of small surface work aimed at the same problem: getting into and around the workspace. Cover images with rich previews and dedicated icons make content browsable, digital twins gained a direct chat link and their own creation option instead of requiring a generic agent first, chat context now survives the jump to fullscreen, and the chat footer was thinned out. July's work pointed outward instead — one-click actions that send a Doc, data point, or Channels idea to the tool where it will be acted on, and a Snowflake integration bringing warehouse data into Channels.

◆ Current state
chattr puts a large language model inside the RStudio IDE, either through a Shiny app or directly at the console. As of 0.3.0 it no longer talks to any model provider itself: all integration goes through ellmer, and the hand-written OpenAI, Databricks and LlamaGPT backends were removed. The package's supported model list is now whatever ellmer supports, and the Shiny app streams responses through ellmer rather than managing a background process.
◆ Where it's heading
The first two releases show why that happened. Each provider brought its own error formats, token discovery and response handling, and 0.2.0 is largely a list of per-provider repairs — OpenAI error parsing, Copilot token discovery and model defaults, a new Databricks foundation model backend. Maintaining that surface scales linearly with the number of providers, and the pivot to ellmer trades it for a single dependency. The cost shows up immediately in 0.3.1, which exists solely to absorb a change in ellmer's token object.
◆ Prediction
Expect chattr's releases to now track ellmer's, as 0.3.1 already does, with the package's own work concentrating on the IDE experience rather than model connectivity. New provider support will arrive without a chattr release at all.
Dovetail
5.0ANALYTICS
Dovetail spent July opening doors to other tools and August making its own rooms easier to enter.
◆ Current state
August has been a run of small surface work aimed at the same problem: getting into and around the workspace. Cover images with rich previews and dedicated icons make content browsable, digital twins gained a direct chat link and their own creation option instead of requiring a generic agent first, chat context now survives the jump to fullscreen, and the chat footer was thinned out. July's work pointed outward instead — one-click actions that send a Doc, data point, or Channels idea to the tool where it will be acted on, and a Snowflake integration bringing warehouse data into Channels.
◆ Where it's heading
The digital twin is quietly becoming the product's front door. Three separate releases this month reduced the friction of creating one, sharing one, and holding a conversation with one, which is more attention than any other surface received. Around it the interface is being simplified rather than extended — fewer controls in the footer, previews instead of lists, context that persists across views. Nothing in this window adds a capability; the whole month is about making existing ones reachable.
◆ Prediction
Expect the sharing path to keep widening — permissions, guest access, or an embed for a twin link — since a link that opens straight into chat only pays off if it can safely leave the workspace.
